I love to see where those will be in a few years. These multitouch screens open new possibilities with Interaction design. It is much easier to get intuitive computer programs. It can get rid of the whole screen, mouse, keyboard triangle.

Just watch the video here:

It looks like its inspired on the tactapad. Which was only missing the direct screen connection.

Asking yourself when you can use those screes yourself? Here are some recent Apple patents:

• Interaction: http://hrmpf.com/wordpress/48/new-apple-patents
• Screen sensor: http://hrmpf.com/wordpress/38/apple-integrated-sensing-display
  (which could also make possible a scanner that directly scans a picture by holding it on the screen)
• Other sensing technology: http://hrmpf.com/wordpress/51/apple-multipoint-touchscreen
• Onscreen keyboard: http://guides.macrumors.com/Gallery_of_Touch_Screen_Interface_Patent

I love to see where the future goes with these new technologies. But all we thought was standard on computers may be a thing of the past very soon.
